Some of the indications of Alzheimer’s disease are quite similar to the general memory loss and forgetfulness that many people experience as they age. Such similarities sometimes lead family members to unnecessarily worry that an elderly loved one is showing symptoms of Alzheimer’s when in fact he or she is exhibiting normal signs of aging. A major distinction that can be made between classic memory loss and Alzheimer’s disease lies in the degree of progression of the symptoms. The onset of Alzheimer’s disease is accompanied by a rapid and dramatic progression of symptom severity, while memory loss caused by age shows a more gradual development. Here we will examine some of the changes that are associated with ordinary memory loss as well as some changes commonly observed in Alzheimer’s patients.



Even the healthiest individuals experience some reduction in memory function with age, which is a completely natural part of life. As a person ages, thinking in general may become slower, and paying attention for long periods of time can become increasingly challenging. A person will likely begin to need more clues than before, such as visual images, words or smells, in order to recall information or events. Additionally, a person experiencing normal changes may also face a decline in the ability to see and hear, and a lessened use of memorization skills. Again, all of these changes are to be expected for the aging mind as long as the advancement is gradual.

While a concrete diagnosis of Alzheimer’s disease is still beyond the realm of modern medicine, doctors can diagnose probable Alzheimer’s disease with incredible accuracy. Alzheimer’s disease involves rapid and drastic regression of brain function that continues to increase in severity over time. While aging can cause a person to forget portions of an event, Alzheimer’s disease can render a patient unable to recall the event at all. Memory loss is severe, and affects a person’s ability to perform familiar tasks. Alzheimer’s patients experience disorientation in time and space, as well as decreased language and communication skills. As their disease progresses, Alzheimer’s patients begin to have difficulty recognizing familiar people, places, and objects, and will eventually require continuous care.

Since memory loss may be completely healthy, may be early signs of Alzheimer’s disease or may be caused by other undiagnosed health problems, obtaining a complete medical and psychiatric evaluation is essential for anyone who is showing signs of dementia.
